ASTM D3551-17 PDF Download

The ASTM D3551-17 standard provides guidelines for preparing soil-lime mixtures in the laboratory. The purpose of this practice is to standardize the preparation process for engineers and researchers interested in studying the effects of lime on soil properties and designing mixtures for construction.

The standard emphasizes the importance of competent personnel, suitable equipment, and appropriate facilities to ensure the quality of the results obtained through this practice. It also highlights that compliance with Practice D3740, which pertains to testing, sampling, inspection, and related activities, does not guarantee reliable results. Factors such as personnel competence and equipment suitability play crucial roles in achieving accurate outcomes.

The practice document states that all observed and calculated values should adhere to the guidelines for significant digits and rounding set forth in Practice D6026. The procedures outlined in this standard represent the industry standard for data collection, recording, and calculation. However, it is noted that considerations like material variation, study purposes, user objectives, and engineering design may require adjustments to the number of significant digits reported.

It is important to note that this standard is not intended to replace education or experience, but rather complement professional judgment. It may not be applicable in all circumstances, and the unique aspects of each project should be considered. The word "Standard" in the title signifies that this document has been approved through the ASTM consensus process.
